Job Description

**About Silent Witness**
Silent Witness is building the AI expert witness for personal injury
litigation.

We use LLMs, vision-language models, and proprietary biomechanical data to
automate accident reconstruction, injury analysis, and research scrutiny —
replacing weeks of expert witness work with instant AI analysis. Think: “GPT
meets forensic science.”

We’re already being used by attorneys in the largest personal injury market in
the U.S. (Los Angeles), and this is your chance to join pre-launch, own the
build, and shape a category-defining legaltech platform.

The founder previously built and exited a legal AI platform, has consulted on
over 1,000 injury cases, and is one of the most recognized biomechanics
experts in the country. You’ll work directly with him to scale the next big
thing in AI + law.

**What You’ll Do**

* Own the entire product stack — from frontend to backend to deployment
* Integrate LLMs (e.g., GPT-4, Claude, Gemini) for reasoning, document parsing, and question generation
* Build visual and document upload flows (image-to-severity scoring, PDF parsing, citation analysis)
* Set up vector search (e.g., FAISS, Pinecone) and cloud infra (AWS/GCP)
* Rapidly ship product features and iterate with real users
* Help build a world-class AI legal platform from the ground up

**Tech Stack**

* Python (FastAPI, LangChain, PyTorch)
* React, Tailwind, Next.js
* OpenAI / Claude / Gemini APIs
* AWS or GCP
* Pinecone, Weaviate, FAISS
* PDF & OCR tools, Gemini Vision, LLM-based retrieval
* GitHub, Notion, Linear (or whatever you like)

**You Might Be a Fit If You...**

* Have 4+ years of full-stack engineering experience
* Have built and shipped real products from scratch
* Have experience with LLMs, embeddings, or AI pipelines
* Are excited to own architecture, not just contribute
* Thrive in fast-paced, ambiguous startup environments
* Want to shape a product already getting legal traction

**What You’ll Get**

* Competitive salary ($100k–$140k depending on experience & equity)
* Equity (0.5–5%) based on experience and role
* Early-team influence, zero bureaucracy, full transparency
* Real ownership over a product that’s solving meaningful problems
* Mentorship and partnership with a founder who’s been there and exited

**Location**

* Remote-first, but ideally San Francisco or Los Angeles for collaboration
* Flexible schedule — outcome > hours
